In 2009, I became aware, via media reports, of the death of David Iredale, a perfectly fit and healthy 17 year old who had died of thirst while on a bushwalk in the Blue Mountains just outside Sydney.

For a tragic event such as this to occur virtually within shouting distance of 5 million people in this modern age was hard to fathom. 

The Coroner’s Inquest was critical...
